Turbocharger Flashcards
1
Q
Purpose of turbocharger
A
To make exhaust gas useful
2
Q
Name the steps
A
Engine air inlet Charger (compressor) Intercooler Engine Waster Gate Valve -> Exhaust OR ->Turbine Manifold Pressure Sensor Compressor
3
Q
What air enters the air inlet
A
Filtered ram air or Unfiltered warm air
4
Q
Purpose of the intercooler
A
Air is cooled to increase power because efficiency is increased through the higher density of cooled air.
5
Q
Why does some exhaust gas bypass the turbine?
A
Waste gate valve allows excess exhaust gas to bypass the turbine and leave via the exhaust. Bypass controlled by the ECU.
6
Q
What does the turbine do?
A
The turbine drives the compressor because it speeds up the air which allows the compressor to take in air faster.
7
Q
Why is there a manifold pressure sensor?
A
The ECU calculates the correct position of the waste gate valve using the manifold pressure sensor.
